Introduction: In this publication we
report estimated changes in carbon stocks for the forests and wood
products of the 50 U.S. states. A first approximation of carbon
status and trends for the forestry sector, these estimates were
developed to assist states in compiling greenhouse gas inventories
for submission (on a voluntary basis) to the U.S. Environmental
Protection Agency (EPA). These initial estimates are designed to
raise awareness of accounting issues, identify common sources of
information and methods, and quantify the approximate contribution
of the forestry sector to a state's status in emitting or sequestering
greenhouse gases. Individual states should view these estimates
as a starting point for developing their own estimates. It is important
to carefully consider the forestry situation in each state by consulting
with local expertise familiar with the most current available data.
Because we used the same methodology and national databases for
every state, more recent data than are included in this report may
be available, and for any particular state, the available data may
support use of different estimation methodology.

Acknowledgments: We greatly appreciate
the technical assistance provided by the FIA staff, including Andrew
Lister, Barbara O'Connell, Tom Frieswyk, Will McWilliams and Carol

for their help with the RPA database. And finally we acknowledge
the reviewers of the EPA report including: Jim Smith, Steve Prisley,
